Product details
Technical Overview of DGMX2-5-PP-AW-E-S-30 Vickers Hydraulic Valve
 
I. Product Overview
 
This valve is astackable pressure-reducing valvefrom Eaton Vickers' SystemStak™ series, primarily used in hydraulic systems tomaintain stable outlet pressureand prevent overpressure in actuators under reaction loads. The model code denotes:
 
  • DGMX2: Series identifier (stackable pressure-reducing valve)
 
  • 5: Nominal diameter (5mm)
 
  • PP: Pressure adjustment method (manual knob with locknut)
 
  • AW: Valve body material (cast iron with rust-proof treatment)
 
  • E: Seal type (enhanced seal)
 
  • S: Installation method (stackable, supports multi-station manifolds)
 
  • 30: Design sequence (specific pressure rating and flow characteristics)
 
II. Key Technical Specifications
 
【表格】
 Parameter Specification
Nominal Pressure 315 bar (maximum pressure rating)
Maximum Flow Rate 60 L/min (standard flow rate)
Compatible Media Hydraulic oil (compatible with explosion-proof wear-resistant hydraulic oil grades 42~48)
Temperature Range 30℃ to 90℃ (standard operating conditions)
Connection Type Stackable mounting (ISO 4401 standard interface compliant)
Material Cast iron body (rust-proof treated, enhanced seals)
Pressure Adjustment Manual knob/locknut/micrometer knob
 
III. Structural Features
 
  1. Design Advantages:
 
      • Two-stage spool design: Dynamically compensates for inlet pressure fluctuations to ensure stable outlet pressure.
 
      • Multi-station compatibility: Supports manifold installation, simplifying hydraulic system layout.
 
      • Modular design: Can be stacked with other SystemStak™ valves to achieve complex function combinations.
 
  2. Critical Components:
 
      • Pressure Adjustment Mechanism: Provides three adjustment methods (knob, nut, micrometer).
 
      • Sealing System: Enhanced seals (high-temperature and wear-resistant).
 
      • Installation Interface: ISO 4401 standard compliant, supports flanged, threaded, or SAE interfaces.
 
IV. Application Areas
 
  • Construction machinery: Pressure control in hydraulic circuits of excavators and cranes.
 
  • Agricultural machinery: Hydraulic system integration in tractors and harvesters.
 
  • Metallurgical equipment: Hydrauli  c transmission systems in rolling mills and presses.
 
  • Special applications: Hydrauli c systems requiring explosion-proof certification (specific certification levels need to be confirmed).
 
V. Installation and Maintenance
 
  1. Installation Guidelines:
 
      • Stacking Order: It is recommended to place the pressure-reducing valve in the middle of the manifold, close to the actuator.
 
      • Torque Requirements: Refer to the screw specification table (e.g., M6 bolt torque is approximately 8-10 N·m).
 
  2. Maintenance Recommendations:
 
      • Regular Calibration: Check the pressure setting every 1000 hours. Adjust if the deviation exceeds 5%.
 
      • Troubleshooting: If the outlet pressure is unstable, prioritize inspecting the spool wear and seal condition.
